The issue of whether civilly committed patients should be extended the right to accept or refuse treatment has generated much controversy and litigation during the past 15 years. In general, the current rule is that in nonemergency situations, individuals who are competent to give informed consent to treatment should be extended the right to refuse it. Obviously, the manner in which this rule is implemented partly depends on how competence to consent to treatment is defined and measured. Most researchers have implicitly assumed that an understanding of treatment information is the sole criterion of competence. It is argued that such a definition may be incomplete and is in need of reexamination. Following a review and analysis of the relevant legal and psychological literature, a comprehensive construct of competency to consent to treatment is proposed and future directions for research are discussed.  相似文献

The traditional separation of health care delivery and financing systems is breaking down as various new types of health care facilities are established and as payment continues to be a major concern. Group Health Cooperative of Puget Sound (GHC) was organized as a prepaid group practice system responsive to consumers. Costs, methods of payment and delivery of care are interrelated and are all influenced by consumer ownership. GHC has been refining its benefit programs since 1945. Strategies for controlling use and costs focus on improved provider management and on flexibility. This article explains how the structure of GHC benefits the consumer.  相似文献

A split-ballot experiment shows that, when people are asked how interested they are in following political campaigns, their response depends not only on the order in which the question is asked, but also on the broader electoral context in which it is posed. When asked how interested they were in following the political campaigns immediatelyafter a question about whether or not they voted in the (1982) election, people were more likely to think they were interested in the campaign, especially if they claimed to have voted, than if they were asked about it immediatelybefore the question on whether or not they voted. This order effect, however, appears to depend onwhen the questions are asked. If asked within a few weeks after the election, there is little or no order effect. But later, as the memory of the campaign fades, the order of the questions makes a sizable difference in the results. This order effect also seems to be more pronounced among better-educated respondents, suggesting that they are more likely to feel pressured by a social norm to vote and to express an interest in political affairs, not only in real life, but in the survey interview as well. The paper concludes with a brief discussion of the implications for the design of the interview schedule used in the American National Election Studies.The research reported in this paper was supported by a grant from the National Science Foundation (SES81-11404).  相似文献

Defining risk   总被引:6,自引:0,他引:6  
Risk is the focal topic in the management of many activities and technologies. For that management to be successful, an explicit and accepted definition of the term risk is essential. Creation of that definition is a political act, expressing the definers' values regarding the relative importance of different possible adverse consequences for a particular decision. Those values, and with them the definition of risk, can change with changes in the decisionmaker, the technologies considered, or the decision problem. After a review of the sources of controversy in defining risk, a general framework is developed, showing how these value issues can be systematically addressed. As an example, the approach is applied to characterizing the risks of six competing energy technologies, the relative riskeness of which depends upon the particular definition used.  相似文献
